Pneumatic Spring Return Actuator (Rack & Pinion)

Pneumatic Spring Return Actuator

ESR Series, Model 7901/7921

Econ Rack & Pinion Pneumatic Spring Return Actuators have aluminum body is hard anodized inside and out to provide maximum resistance to abrasion and corrosion. The hardened electroless nickel plated carbon steel shaft is blowout proof and corrosion resistant. Every actuator has adjustable travel stops which allow a full ±5˚ travel adjustment between 85˚ and 95˚. These travel stops are designed to absorb the maximum rated torque of the actuator and maximum impact loads associated with recommended travel speeds. The Spring Return models are fully compliant with ISO 5211 & VDI/VDE 3845 standards, are outfitted with stainless steel bolts and fasteners and are available in 14 different sizes.

Full Travel (0-360) Worm Gear

Full Travel Worm Gear

Our Full Travel Worm Gear can be manually set to any rotation from 0° to 360°. This multi-turn worm gear is ideal for sluice gates and dampers. They are widely used in applications that require partial stroke field adjustments where full degree travel is restricted.

Stainless Steel Worm Gear

Stainless Steel Worm Gear

Our full cast stainless steel worm gear is available from stock. This quarter-turn worm gear is designed for low torque manual applications, and is suitable for butterfly valves, ball valves and plug valves.

Manual Bevel Gear – B Series

Manual Bevel Gear – B Series

The Diamond Gear B Series a versatile and economic choice for manually operated bevel gears. The B Series enables the user to modify valves with a torque only gear operator. This gear is designed to handle torque only.

Widely used by machine shops, the B Series provides a cost effective way to add gears to handwheel operated valves. The B Series is designed for sluice gate valves, gate valves and globe valves.

Motorized Bevel Gear – BG Series

Motorized Bevel Gear – BG Series

With over 438 thousand pounds of thrust our BG Series is rugged and designed to operate a variety of multi-turn application such as gate valves, globe valves and sluice/slide gate valves. The heavy-duty ISO motor flanges and waterproof design are standard on all models.

Declutchable Manual Override Gear, DG Series

Declutchable Manual Override Gear, DG Series

The DG Series features a “sandwich” style declutchable worm gear that works in conjunction with pneumatic actuators. These gears provide manual override capabilities when air supply to the actuator is interrupted. The DG Series is ideal for critical applications where an emergency situation may arise.
